I am attempting to port the KBOOT v1.2.0 to a K21F processor (MK21FN1M0AVLQ12). I have done this port before with the previous version of KBOOT successfully. It seems that the new version of KBOOT requires updated board specific CMSIS files, which I do not have. Are these files available yet for my processor, so that I can continue my port? Or should I just stick with KBOOT v1.1.0 for now?
Also, I am required to get USB working with the bootloader, and I noticed that there are board specific files for the usb_stack as well. Are there equivalents for the K21F? or should I just try to copy and modify the files from an existing processor? (I have been porting from the MK22F512 version of KBOOT).
